Abstract: A bicycle support comprises a socket to be secured to the horizontal rear fork members of a bicycle frame, a support arm having one end pivotally connected to said socket for tilting movement of the arm from a position of rest into operating position and held in one or the other of said positions by a tilting spring acting eccentrically on the arm with respect to its pivoting axis to urge the arm against an abutment on the socket, a spring counterbearing being associated with said pivotally connected end of the arm. The spring counterbearing is formed by an arched surface, for example by the surface of a ball lodged in a trough formed on the pivotally connected end of the support arm, or by a concave arched surface of the trough itself.
